JAMES RICHARD VINDMILL, OF BRIERLEY HILL, COUNTY OF STAFFORD, ASSIGNORTO DAN RYLANDS, OF BARNSLEY, ENGLAND.

MOLD FOR GLASS BOTTLES, JARS, AND OTHER LIKE ARTICLES.

SPECIFICATION forming part of Letters Patent No. 416,389, dated December3, 1889.

Application filed January 14, 1889. Serial No. 296,369. (No model.)Patented in England .Tune 29, 1886, No. 8,526.

.To @ZZ whom it may concern.

Beit known that I, JAMES RICHARD WIND- MILL, a subject of the Queen ofGreat Britain, residing at Brierley Hill, in the county of Stafford,England, have invented new and useful Improvements in Molds for GlassBottles, Jars, and other Like Articles, (for which I have obtained apatent in Great Britain, No. 8,526,bearing date June 29,1886,) of whichthe followingis a specification.

My invention consists in manufacturing glassbottles and glass jars andother like glass articles by the combination of the processes ofpressing and blowing, as hereinafter described.y

My invention consists, further, of the apparatus hereinafter described,to be used in conducting the said pressing and blowing processes.

I will describe my invention as applied to the manufacture of glass jarsand glass bottles in conjunction with the apparatus which I prefer touse.

The apparatus consists, essentially, of a sliding vmold in which thepressing of the glass article is effected and a second or outer moldsurrounding the sliding mold, in which second mold the pressed articleis blown and the required form given to it. The sliding pressing-moldconsists of a cylinderhaving a cavity or mold .of the required vshapemade in it, the said sliding mold working through an opening in thebase-plate of the apparatus. The rising and falling Inotion of thesliding mold is effected by a lever, the said mold, when raised withinthe blowing-mold, being held in that position by a catch engaging A withthe lever of the sliding mold. On the base of the apparatus theblowing-mold is supported, the said mold being divided vertically into,two halves, hinged together at back, the said halves when closed beingheld together by a catch. .Iointed to an upright at one side ofthebase-plate of the apparatus is a cover by which the compound mold isclosed, the said cover being held down by a catch. Through this cover apressin g-plun ger for operating upon the melted glass in thepressing-mold Works, the said plunger being jointed to a lever, and thelatter to a link connected to the upright to which the cover is jointed.A coiled spring1 between the plunger-lever and the cover describedraises the said plunger from the mold. The top of the blowing-mold isprovided with a neck orv contraction in which the neck of the glassarticle being made is formed.

Vhen the article is being blown in the outer mold, the said mold isclosed air-tight by a conical cap or cover on the end of theblowing-pipe, the said cap or cover fitting in the open end of the moldand top of the article and accurately closing them.

Instead of combining the pressing-mold and the blowing-mold in the sameapparatus, the two molds may be used apart, substantially in the mannerdescribed, for the pressing and blowing operations.

The glass jar or glass article to be made is first pressed into aroughly-formed article in vthe pressing-Inold, and its shape isperfected and iinished by blowing it in the second or blowing mold.

I will now proceed to describe with reference to the accompanyingdrawings the manner in which my invention is to be performed. Y Figure lrepresents in side elevation apparatus constructed according to myinvention for the manufacture of a glass jar or bottle according to mymethod, the said apparatus having combined in it the sliding pressing-.'nold and the jointed or hinged blowingmold; and Fig. 2 represents thatpart of the apparatus which is combined with the apparatus, Fig. l,during the blowing or linishing stage of the glass jar or bottle, ashereinafter described. l f a is the pressing-mold, capable of a slidingmotion, and l) is the second or outer mold, made in two partshingedtogether at back. The blowing-mold b is -supported on the baseplate c,the sliding pressing-Inold a working through an opening in the saidbase-plate c. In Fig. 1 the sliding pressing-mold a, is represented inits raised position, and the blowing-mold b is represented closed. Thesaid blowing-mold b is furnished at top with the neck or contraction h2,in which the neck of the glass jar or bottle is formed, and the saidblowing-mold is opened and closed by means of handles, (notrepresented,) and when closed the two parts are fastened to- TOO gethcrby a catch. The rising and falling motion oi the slidingl pressing-molda is effected by the lever d, the said mold a being supported in itsraised position within the blowing-mold b by the catch e engaging withthe lever (l of the slid-ing mold, as represented in Fig. l. f

71. is the cover by which the combined mold (t b is closed, the saidcover being jointed at 71? to the upright g. 'lhe cover t when loweredis held down by the catch t', engaging in the depression h3 in thehandle part of the cover.

7u is the pressing-plunger for operating' upon the melted glass in thepressing-lnold a, the said plunger working through the hinged cover 71.The plunger 7u is jointed at Z2 to the lever l, and the latter to a linkm, jointed to the upright g. By means of the coiled spring n, betweenthe lever t and plunger-lever Z, the said plunger 7c is raised from themold a.

s is a slide or sliding plate for closing the opening in the base-platec after the pressing-mold a has been depressed and the blowL ing-mold bis about to be used; or, the closing of the opening in the base-plate cmaybe eiiected by turning the blowing-mold b to a part of the base-platehaving no hole in it, the said part of the base-plate in that caseconstituting the bottom of the blowinglnold b.

p, Fig. 2, is the conical cap or cover on the blowing-pipe q, which capand blowing-pipe are used when the article is being blown in the mold b.The cap or cover p iits in the open end of the mold b and top of theartice and accurately closes them.

In making a glass jar according to my invention I proceed as follows:The sliding pressing-mold a is raised into the outer blowing-mold b bythe hand-leverd, and the said mold ct is supported in its raisedposition by the catch e engaging with the hand-lever d, as represented.The halves of the blowingmold b are next closed by their handles andfastened together by the catch. The melted glass being placed in thepressing-mold @the cover and plunger h 7c are brought down and the saidcover fastened in its place by the catch t'. By operating the plunger Itby its lever Z the lnelted glass is pressed and fashioned in the lnolda, a lportion of the glass being forced into the neck b2 of the outer orblowing mold ing raised and thrown back, the sliding' mold a isdepressed through the base-plate c, leaving the pressed glass articleattached by its neck to the neck b2 of the blowingmold b. The opening inthe base-plate c, through which the sliding mold is withdrawn, havingbeen closed by the slide or sliding plate s or The cover and plungerbethe mold b turned onto an imperforated part of the base-plate c, thecap or cover 7l, Fig. 2, of the blowing-pipe q is fitted into the top ofthe blowingmold b and article,and the pressed article is now blown inthe said mold in the ordinary way of blowing glass articles. The cover7L being removed and the blowing-mold opened upon its hinge, the glassjar or bottle is removed and the operations described are repeated. Inthis manner the melted glass is iirst pressed into a roughly-formed jaror bottle and the pressed jar or bottle afterward completed by blowingit in a second mold.

Although in the accompanying drawings I have represented the apparatuswhich I prefer to use in carrying my invention into effeet, and which Ihave found to answer well in practice, yet I do not limit myselfthereto, as other kinds of apparatus may be employed in conducting mymethod of manufacture.

lVhat I claim as new, and desire to secure by Letters Patent, is-

1. The combined mold a Z1, having a sliding pressing-incid it, with arising and falling action, as described, working within an outerblowing-mold Z), such mold b being supported lon the base-plate c, andbeing furnished at the top with the neck or contraction b2, and themovable cap j), the said combined mold a l) being capable of beingclosed during the pressing operation by the common cover 7l.,substantially as and for the purposes described.

2. The cover t of the combined mold a b, operating as described.

3. The sliding pressing-mold a., having a rising and falling action, asdescribed, in combination with the outer blowing-mold b, substantiallyas and for the purposes described.

al. The combination of the sliding pressingmold a, blowing-mold b,plunger lr, cover p, and blowing-pipe q.

5. The'combined mold a l), in combination with the base-plate c, coverp, and blowingpipe q, substantially as described.

The combined mold (t l, in combination with the plunger 7c,plunger-lever l, and spring n, substantially as described.

7. The combined mold (t l), in combination with the base-plate c,plunger 7c, plunger-lever cover p, and blowing-pipe q, substantially asdescribed.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
